[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [24336] trunk/blender: Added mass and spring vertex groups to softbody rna/ui

[bjornmose]

Hi Matt
I'd like to give you a big  'Thank you' .
This looks generic enough to be a template for
'blender developers wiki' : How to plug an object ( or what ever  ) 
property to the blender UI .
Well, may be I missed existing docs, but then they are not clearly 
visible on the blender.org page, which i would choose for 1rst 
developers information ( as if i don't know 42th Murphy's law:  "The 
information you look for is never at the place you would expect it to 
be, but pretty close to the other end of the known universe" )
So point the flame thrower on me .. (i am used to it)  .. still .. 
search engines  will find this and may be help other coders to ship 
trough /Skylla/ and /Charybdi/s
at ease.
